Continuation of application Serial No. 590,545, filed September 21, 1922. This application le `April 16, 1923. Serial No. 632,465.

i This invention relates to furnaces, and

more particularly to such'furnaces as may be sin" operation controlled .at eac-h mold.

used for melting brass and other metals and pouring the same into molds.

This ap lication is a continuation of application erial Number 590,545, filed Sep-ff tember 21, 1922.-

In the service for which this device is intcnded,it is usually reljuired, after properly 1' melting the'y metal in he crucible, to pour -nthe same into molds. These molds are usually placed in a row or circle, and the metal poured into them in succession, the c-rucl'ble being moved from one to another. -In perlo forming the operation of pouring; it is necessary Eto control the stream of metal in such a way that not only will the rate of pouring be such as will be best adapted to the size and nature of the mold, but the 2H stream must beproperly controlled so that it will flow into the mold directly and not be spilled over the sides. As the form of the stream of metal .changes during the poiiring on account of'changes in the posi' l5 tion of the crucible `and on account of change in the head of metal over the pourin spout as the amount of metal in the crucile (lecreases, it is desirable that the operator shall have such complete control of the tipping of t el ciuoible that he can control both the lrate of pouring and also the position i of the stream with respect to the mold.l One of the objects of this invention., therefore; is to provide means for handling j the Crucible, such that the operator will have `complete ycontrol ofthe tippingmovement thereof andjof its position with respect tog the mold. j

'Another object of this invention 'is to provide such means which `will enabley the operator to cont-rol the tipping of the cruoible `and also its elevation at the same time.

Another object of this invention is to provide Isuch means whereby the' operator may Vcontrol such tipping andI elevating 'movements of the crucible, either' independently or simultaneously, and in either Y direction. .A

Another Lobject of Avthis invention is 4to provide an electrically heated cruc-ible and amounting for the same, whereby yit may -ing spout with.l re

lsector A18 for a vinafter describe *urther objects 'will appear from the detail description taken in connection with the accompanying drawings,rin which:

`Figure 1 represents a front elevation of a furnace embodying this invention; and

Figure 2 represents a side elevation of the same. r j

Referring to the accompanying drawings, 1 designates a' mold which may be' of any form, such as an'ingot mold for casting steel-billets. or the, like. 'A seriesof these molds may be arranged along a track 2' which may be laid on the foundry Hoor or in u trench or`pit prepared for vthat purpose. 11. is arranged to run along the track 2, a motor 5 being provided yto drive the same along thetrack.

A `carriage',provided .-with wheels be moved from mold to mold and theipour-` The carriage 3 is provided with a pair 'I ot cross-rails 6 upon which a frame 7 provlded with suitable wheels 8 is adapted to movef" The rails 6 need be only long enough to provide a limited movement of the frame 7 for adjustment of the position of the pour ect to the mold inl a lateral direction. he frame 7 comprises a sub-structure 9 mounted on the wheels 8 and uprights l() properly framed together at the top by cross-braces lllso as to provide a strong and rigid structure.A One pair of4 sov uprights 10 is provided with guide-ways."

12 within which'cross-heads 13 are adapted to-move up and down. Thesecross heads are provided with journals 14 upon which are pivoted brackets 15. Bolted to each of.

the brackets 15 are sub-brackets 16 and 17 which together are adapted to provide a The sector 18' is rovidedwith brackets 19 by means of whicii thecruoible 20 may be mounted upon the sector so as to be carried thereby. J'

purpose which will be `herej The cross-heads 13 are suspended from thef i fname 7 by means of cables 21passin'g over drums 22,- both ofwhich' are mounted on a shaft 23 journalled to the frame `7. The

shaft 23 is connected through proper reduction gearing 24vto va motor 25, so that by and operating the motor 25, the cross-heads 1 3 may be raised and lowered. A second pair of cables 26"J is provided which are attached to the'sectors 18, and after passing around the circumference of said sectors, pass up over a pair of`drum's`27 mounted `on a shaft 23 which is also'journalled on the frame 7.

',The shaft 28 is connected through reduction gearing 29 to a motor 30 -by means of which the drums 27 m'ay be operated so" as to take up or pay out the cables 26 for the urpose of ti ping the crucible 20. VIt will be ap arent t at by operating the drums 22 ,the cables 21 and 26 may be raised Iand lowered. Raising or lowering the cables 21 will correspondingly moveithe pivots 14 so as to raise or lower the crucible 920.

\is ka sprocket 34 whichdrives a sprocket chain 35, running over a sprocket 36, on a screw shaft 37. The screw f shaft 37 is threaded into a bracket 38 mounted on the carriage 3.. The sci-eu7 shaft 37 isitself, mounted in "a bearing 39 on the sub-structure -9 of the frame '7. By turning the handle 33, the Screw 37 may be operated to move the frame 8 backward or forward along the track. 6 so as to adjust the position of the pouring spout 40 of the crucible 20` to proper relation with the mold 1.

"An electric furnace of the induction type is shown'yin the drawings, although the invention may be used with any other type Vof furnace. In order to provide current for the operation of thefurnacafa pair ofxfeed2 ers in the shape 'of contact rails 41 is pro-` vided. These may be mountedupon insulatorsA 42 suitably mounted in a covere l trench '43 in a well known manner. Mounted 1 The collecting vthrough flexib on a bracket 44 on the carriage 3 is a pair of collecting shoes 45 adapted to engage 'the The operator may then adjust the position of the s out 40 to the desired relation with the mol A 1. The motors 25 and 30 will then be operated either simultaneously `or inde-n pendent of one another, so as to first raise or'lower the spout- 40 to the desired position with respect to the mold and then to tip the Crucible so as to pour then metal into thef4 mold. It will /be apparent that absolute control of the stream of metal is provided by themotors 25 and 30. yBy operating these motors the crucible'ma be raised, lowered or tipped in any desire Amanner so that the` position and volume of the stream of metal f may be controlled to a nicety. The operator "so may thus fill the mold without loss of metal by spilling and at the proper rate of flow. The change from one mold .to another is rapidlyV .and conveniently made by mere manipulation ofthe controllers l50, 51 and 52 which control the' motors.`\

It isobviou's that various changes may be made in details of construction without departing from the spirit of this invention; it

1s, therefore, to b understood that thislin- 90 vention is not to b limited to the specific details described and shown.
